Not sure, have to look into it.

> Is one link per slide appropriate? Wouldn't one link per presentation suffice? If the links were the same I think that this may be overkill

Well the idea is that you get a deep backlink with the subthread, i.e. you jump directly into the discussed slide.

People might come via a search engine to a subthread and can navigate directly to the slide (or video time mark).

This needs to be prepared.

> IMHO a simple link to a video would be better, allowing users to choose how to view it rather than auto loading (if this is what you intend) a video. From experience this would also be better for low end devices in terms or resource usage.

Hmm, this should be configurable ... default could be to just show a pic from the first slide from slideshare or youtube and after clicking the embedding might be started.

A prototype for this should be pretty easy realizable with a nodelet-hack.

I.e. after finding a link to YT or SS a preview or embed might be loaded, according to privat options set in the free nodelet.
